NIH Rare Diseases : ⁵⁴ Mucopolysaccharidosis type IIID (MPS IIID) is an genetic disorder that makes the body unable to break down large sugar molecules called glycosaminoglycans (GAGs, formerly called mucopolysaccharides). Specifically, people with this condition are unable to break down a GAG called heparan sulfate. Affected individuals can have severe neurological symptoms, including progressive dementia, aggressive behavior, hyperactivity, seizures, deafness, loss of vision, and an inability to sleep for more than a few hours at a time. MPS IIID is caused by the missing or deficient enzymeN-acetylglucosamine 6-sulfatase. MPS IIID is inherited in an autosomal recessive manner. There is no specific treatment for this condition. Most people with MPS IIID live into their teenage years, and some live longer.

MalaCards based summary : Mucopolysaccharidosis, Type Iiid, also known as mucopolysaccharidosis type iiid, is related to mucopolysaccharidosis iii and mucopolysaccharidosis-plus syndrome, and has symptoms including seizures, joint stiffness and diarrhea. An important gene associated with Mucopolysaccharidosis, Type Iiid is GNS (Glucosamine (N-Acetyl)-6-Sulfatase). Affiliated tissues include bone and eye, and related phenotypes are low-set ears and short neck

OMIM : ⁵⁸ The mucopolysaccharidoses are a family of lysosomal storage diseases caused by deficiencies of enzymes required for the catabolism of glycosaminoglycans. The defects result in accumulation of excessive intralysosomal glycosoaminoglycans (mucopolysaccharides) in various tissues, causing distended lysosomes to accumulate in the cell and interfere with cell function. Multiple types have been described (Mok et al., 2003). (252940)

UniProtKB/Swiss-Prot : ⁷⁶ Mucopolysaccharidosis 3D: A form of mucopolysaccharidosis type 3, an autosomal recessive lysosomal storage disease due to impaired degradation of heparan sulfate. MPS3 is characterized by severe central nervous system degeneration, but only mild somatic disease. Onset of clinical features usually occurs between 2 and 6 years; severe neurologic degeneration occurs in most patients between 6 and 10 years of age, and death occurs typically during the second or third decade of life.
